The City: Suggestions for the investigation of human behavior in the city environment
(1915)
“ Some of the first things we want to know about the city, therefore, are: sources of population; immigration and natural growth; distribution of population within the city as affected by (a) economic, i.e., land, values, (b) sentimental interests, race, vocation, etc.; comparative growths of the population within different portions of the city area, as affected by birth- and death-rates, marriage and divorce, etc. The neighborhood.—Proximity and neighborly contact are the basis for the simplest and most elementary form of association with which we have to do in the organization of city life. ”
